I've tried "lady speed stick", "secret", & "certain dri." Lady Speed Stick and Secret were suppose to stop the musty smell for 24 hrs. However, I sweat too much on my underarms so I switched to Certain Dri. I still sweat everyday even when I put it on that morning. Any suggestions?

There is a prescription AP called Drysol that might do better than the Certain Dri for you. Also, sometimes Glycopyrrolate is prescribed for drying things up.

Check with your Dr.

Hope this helps,
